UnverifiedPrivilege Separation is a classic principle in operating systems and security engineering, whereby different components are granted the minimum permissions necessary to fulfill their responsibilities.71% similarVerifiedPermissions that appear harmless when held individually by an agent (such as reading files and calling an HTTP library) can enable data exfiltration when combined, which is the tool-combination emergence problem.69% similarUnverifiedWhether runtime security can protect Agents that can bypass the gateway depends on its definition: if it is merely policy code inside the gateway, it cannot protect them; if it is a defense-in-depth system covering credential management, network isolation, and token issuance, it can provide a fallback.68% similarUnverifiedDefense approaches for multi-agent security include applying independent content safety review to inter-agent messages, the principle of least privilege, message source authentication and integrity verification, and trust boundary model isolation.67% similar
